Earth periapsis distance
An apsis is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, for orbits about the Sun the apsides are called aphelion (farthest) and perihelion (nearest). See more There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ap-, apo- (from ἀπ(ό), (ap(o)-) 'away from') for the farthest or peri- (from περί (peri-) 'near') for the closest point to the See more The perihelion (q) and aphelion (Q) are the nearest and farthest points respectively of a body's direct orbit around the Sun.
